Explanation:

Algae blooms are often caused by eutrophication. Eutrophication occurs when there is an excess of nutrients, especially nitrogen and phosphorus. Surface runoff from fields typically contains fertilizers. Fertilizers are rich in nitrogen and phosphorus. When these nutrients enter the lake, they act as a food source for algae, allowing them to grow rapidly and cause blooms.

I think the eutrophication is caused by nitrogen and phosphorus from fertilizers in the surface runoff.
